Sir: According to the traditional accounts of European psychiatry,
true hallucinations are apparent perceptions of an external
object in the absence of adequate sensory stimuli. Conversely,
Sims states that Kandinsky and Jaspers described pseudohallucinations
as a separate form of perception from true hallucination.
Pseudohallucination is a perceptual experience that is figurative,
not concrete or “real,” is located in inner subjective space, and is
perceived with the “inner” ear (or eye) (Table 1).
